ATTACHMENT FOR ROCKING-CHAIRS.

Application filed December 11, 1915.

To all whom it may concern:

Be 1t known that I, ALEXANDER FRAZIER,

a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon; have invented certain new and useful Improvements in Attachments for Rocking-Chairs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to an attachment for rocking chairs.

The object of the present invention is to provide for rocking chairs, a simple, practical and comparatively inexpensive attachment adapted to be readily applied to an ordinary rocking chair and equipped with means for automatically forcing air against the upper portion of the body and face of the occupant while the chair is being rocked.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out int-he claims hereto appended, it being understood that various changes inthe form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawlngs Figure 1 is a front elevation of a rocking chair provided with an attachment constructed in accordance with this invention,

Fig. 2 is a longitudinal sectional View of the same,

Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 2,

Fig. 4 is an enlarged detail sectional view illustrating the manner of securing the flexible portion or bag of the bellows to the bottom of the rocking chair.

Fig. 5 is a detail view of one of the springs.

Like numerals of reference designate cor responding parts in the several figures of the drawings. 7

In the accompanying drawings in which is illustrated the preferred embodiment of the invention 1 designates a bellows comprising a flexible body or bag 2 secured at the upper edges of its flexible wall 3 1n a groove 4 in the lower face of the seat 5 of a rocking chair 6. The flexible body or bag Specification of Letters Eatent.

of the bellows is secured in the groove l by a strip 7 of suitable flexible material and fastening devices 8 which pierce the flexible strip and the bag or body of the bellows as clearly illustrated in Fig. 1 of the drawings. The bottom of the rocking chair constitutes one of the members of the bellows and a lower relatively movable member 9 consisting of a rectangular board is secured to the bottom of the bag and constitutes the coacting member of the bellows.

The bellows communicates with passages 10 extending through the bottom of the seat of the rocking chair and through the support or bar 11 of the arm 12 of thechair and having inclined upper terminal portions or nozzles 13 which direct the currents of air upwardly and inwardly toward the upper portion of the body and the face of the occupant of the chair. The passages may extend to any other desired portion of the rocking chair and any other suitable means may be employed for directing the current toward the occupant.

The bellows is maintained normally eX- tended by springs 14: located at opposite sides of the chair and located without the bellows and interposed between the lower face of the bottom of the chair seat and the relatively movable lower member 9. The springs 14 are adapted to be compressed by the means hereinafter described on one movement of the chair and they operate to expand the bellows on the opposite move ment of the chair whereby air will be forced through the passages 10 and discharged in currents on the occupant.

'The bellows is equipped with a depend ing operating member 15 adapted to contact with the floor or other supporting surface and consists of a rod provided at its lower end with a buffer 16 and connected at its upper end with a coiled spring 17 preferably formed integral with the rod and secured to the lower member of the bellows as clearly illustrated in Fig. 2 of the drawings. The buffer preferably consists of a head of rubber having a socket to receive the lower end of the rod or member 15.

The spring may be connected with the rod or member 15 in any other desired manner and the upper terminal 18 of the spring is preferably threaded and engages a threaded opening 19 in a metallic cleat or bar 20 secured to the lower face of the lower member 9. By this construction, the rod or member lower arms 21 and 22 anda connecting coil 23. The terminal 24 of the upper arm is embedded in the lower face of the seat and the terminal portion of the lower arm is bent to form a hook 25 for engaging the bellows at the bottom thereof. The springs are located at opposite sides of the bellows and they can be arranged either interiorly or exteriorly of the same. It is preferable, however to arrange the springs exteriorly of the bellows and to engage the hook 25 with a headed projection 25. This will enable the springs to be readily detached when the bellows is hooked up as hereinafter explained and the bellows may then be hooked up without being resisted by the tension of the springs,

The bellows may be supported in an elevated position by a hook 26 and an eye 27, the hook being preferably carried by the seat of the chair and the eye projecting from the lower section of the bellows as clearly illustrated in Fig. l of the drawings. This will support the rod or member above the supporting surface or floor and will enable the rocking chair to beoperated or rocked without actuating the bellows. The bellows may be equipped with any suitable valve 28 adapted to close automatically when the relative movement of the chair seat and the bottom of the bellows is toward each other and to open when the movement of the parts is in the opposite direction.

What is claimed is l.'The combination of a rocking chair, a

bellows secured to the under side of the seat of the rocking chair, said seat constituting the upper member of the bellows, springs located at opposite sides of the bellows and connected with the upper and lower members thereof for opening the bellows, and an operating rod extending downwardly and forwardly from the lower member of the bellows and secured at its upper end to the same and arranged to be carried into and out of contact with the floor by the rocking movement of the chair for operating the bellows, said operating rod being spirally coiled for a portion of its length to form a cushioning spring and the upper end of the latter being arranged contiguous to the lower member of the bellows.

2. The combination of a rocking chair, a bellows secured to the under side of the seat of the rocking chair, said seat constituting the upper member of the bellows, springs located at opposite sides of the bellows and connected with the upper and lower members thereof for opening the bellows, and an operating rod having a threaded upper end. and extending downwardly and forwardly from the lower member of the bellows so as to be carried int-o and out of engagement with the floor by the rocking'of the chair for operating the bellows, said lower member of the bellows having a threaded opening to receive the threaded upper end of the rod and the rod being spirally coiled contiguous to the lower member of the bellows to form a cushion and also to limit the penetration of the threaded portion of the operating rod.

In testimony whereof I affix my signature in presence of two witnesses.
